Abstract A high incidence of bacterial infections has been previously reported during interleukin-2 (IL-2) treatment, mainly due to catheter-related infections. Antibiotic prophylaxis has been successfully used to decrease such infections. The goal of this study was to evaluate an alternative way to reduce catheter-related infections in IL-2-treated patients by the use of totally implanted catheters. A total of 74 patients with metastatic renal cell carcinoma, referred to our institution to receive IL-2 from March 1989 to July 1991, were included in this prospective study. IL-2 was given on a 2-days-a-week schedule (24x106 IU m-2 day-1) either alone (41 patients) or in association with interferon γ (33 patients). All these patients were prospectively evaluated for fever, bacteremia and line-site infection. Seven patients (9.5%) had one (2 patients) or more (5 patients) positive blood cultures with Staphylococcus aureus. Antibiotics were used only in 5 patients, and the catheter had to be removed in only 2 of these patients. In the other patients, no further infection developed despite the lack of antibiotics. Moreover, 9 patients had positive blood cultures with Staphylococcus epidermidis (1.9% of total number of blood cultures). In conclusion, a totally implanted catheter appears to reduce the incidence of infections in IL-2-treated patients, at least on a 2-days-a-week schedule.
